Dau coroana vă rog repede!!!!

Answer 1

2007+18:[2+(16-108:27):3]
=2007+18:[2+(16-4):3]
=2007+18:(2+12:3)
=2007+18:(2+4)
=2007+18:6
=2007+3
=2010

3+3×[3+3:3×(3+3×3)]:15
=3+3×[3+1×(3+9)]:15
=3+3×(3+1×12):15
=3+3×(3+12):15
=3+3×15:15
=3+45:15
=3+3
=6

812-4×[6×(61-3600:12:30)]:9
=812-4×[6×(61-300:30)]:9
=812-4×[6×(61-10)]:9
=812-4×(6×51):9
=812-4×306:9
=812-1224:9
=812-136
=676
